SPECIFICATION forming part of Letters Patent N0. 720,282, dated February 10, 1903.

Serial No. 117,370. (No model.)

fumigators and in which the'destruction of` the pests is effected by means of noxious smoke or vapor. Y

My invention has for its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability, and general efficiency.

With these ends in View my invention consists in the` improved construction, arrangement, and combination of parts which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, lFigure 1 is a sectional elevation of a vermin-destroyer constructed in accordance with myinvention. Fig. 2 is a detail sectional view taken on the line a; a: in Fig. 1. I

Corresponding parts in the figures are indicated by like numerals of reference.

My improved vermin-destroyer is usually and preferably mounted upon a platform 1, having axles 2 and supportingwheels 3, whereby it may be readily transported from place to place. Uprights 4support a fan-case 5, containing a fan or blower 6, the shaft of which,7 ,is provided with a pulley 8, connected by a belt or band 9 with a drive-Wheel 10, suitably mounted upon a shaft 11, supported between the uprights 4 above the fan-case. In order to bring the parts closely together, the drive-wheel may be set to one side of the fan-case, as shown in the drawings; but this is not necessary, although desirable in order to economize space. The shaft 11 is equipped with a crank 12, by means of which it may be operated.

The fan-case 5 is provided with a tapered extending from the rear end of the fire-box. The latter is preferably constructed with tapering ends, as clearlyshown in the drawings, and it is provided on its upper side witha door 16, through which fuel and ingredients, such as sulfur, calculated to develop noxious odors may be placed in the tire-box. The latter, which is supported upon legs 17, is provided on its under side with a door 18, through whichits contents may be removed when desired. The tapering front end of the fire-box has a forwardly-extending pipe provided with a valve 20. To this pipe is attached a iexible hose 21, which may be inserted into the burrows of the animals to be exterminated, it being found necessary to inject the noxious vapor at a point as close as possible to the lower ends of the burrows in order to achieve the best results.

The spout or nozzle 13 of the fan-case is connected with the fire-box 23 near the lower end of the latter by means of a small pipe 22,

composed of separate sections 22a 22D, connected, respectively, with the nozzle 13 and the fire-box 23 and having their ends separably connected by means of a union 30. This pipe is forthe purpose of supplying an upward draft through the fuel placed in the firebox. Suitably located within and detachably connected with the fire-box is a shield or guard 24, having a horizontal portion disposed directly above and adjacent to the blastopening, which serves to deflect the blast from the fan-spout upon the coals within the fire-box in order that the vapors developed by the noxious ingredients placed thereon may be blown direct to the exit-pipe. Suitably arranged within the re-box, in rear of the exit-opening, is a perforated screen 25, which will prevent the solid contents of the fire-box, such as coals, from being blown into the exit-pipe. This screen, it will be seen, is disposed in the conical or tapering portion of the fire-box and in an inclined position. Being thus arranged, it may be made of an area greatly exceeding that of the dischargepipe, and it will thus perform its intended function with less liability to become choked than if disposed over the opening of the exitpipe only.

The operation of this device and its advantages will be readily understood from the IOO foregoing description, taken in connection with the drawings hereto annexed. It will be noticed that by unscrewing the unions 14 and 30 the fire-box may be detached whenever desired in order to repair it or to replace it with a new one in case it should be burned out. Suitable braces and supports for the parts ofthe device are obviously provided wherever necessary. The device is extremely simple and may be constructed -at a small expense, while it will be found extremely effective in exterlninating vermin of aclass which, as a rule, is difficult to reach.

By closing the valve in the exit-pipe the device may be transported from one place to another without the possibility of the noxious odors escaping from the fire-'box and annoying the operator or operators.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a device of the class described, a rebox having,r tapering, conical ends, a fan-case having a tapering spout, a union connecting said spout with the rear end of the nre-box, an auxiliary jointed pipe connecting the bottom of the fire-box with the tapering spout of the fan-case, and a defiecting-shield within the fire-box at the rear end thereof and having a horizontal portion directly above the discharge of the fan-spout.

2. In a device of the class described, a irebox having tapering conical ends connected at one end with a blower and at the opposite end with a valved discharge-pipe, in combination with a perforated partition disposed within said fire-box at a distance from the discharge end thereof and of an area greatly f JAMES M.
